AT&T today said it has upped speeds with its LaptopConnect users in mind through a set of upgrades to the company's HSPA-based 3G wireless network. The service sees a major boost to upload speeds that increases the peak from 800Kbps to 1.2Mbps, a 50 percent gain which is nearly in line with download speeds. Those download speeds have also increased in overall performance, increasing from a minimum average of 600Kbps to 700Kbps and from a maximum real-world peak of about 1.4Mbps to 1.7Mbps.
